MRI exams can be done:
1. Without contrast (dye) 2. With contrast (dye) 3. With and without contrast (dye)
The majority of MRI exams are done without contrast. Most common reasons for contrast administration include infection, cancer, and after surgery.
FDA approved contrast agents are gadolinium based and are safe to use in patients. However, they can have very harmful side effects if the patient develops an allergic reaction or has kidney disease or kidney failure. Without functional kidneys, the body cannot get rid of the gadolinium from the contrast agent, which can cause a deadly and incurable disease known as nephrogenic systemic fibrosis.

Can an MRA be done without contrast?
Yes, an MRI (magnetic resonance imaging) can be done without contrast, using only the magnetic field and radio waves to create images of the inside of the body. Contrast agents may be used to enhance certain structures or abnormalities in the images, but they are not always necessary for an MRI scan.
How is MRI contrast administered for a brain MRI?
MRI, or Magnetic Resonance Imaging, is an imaging technique using a very powerful magnet and sophisticated detectors or 'scanners' to obtain very detailed images of any part of the body. There is no radiation or x-rays involved. The MRI can be non-contrast, contrast, or both. If both, the non-contrast proceedure is done first. No matter what part of the body is being imaged, the contrast is injected intravenously. A nurse or specially trained technician will start an IV, usually in the arm, and then the liquid contrast material is injected, and the MRI performed.

A CT Scan can image an aneurysm without a contrast injection even though it does better with a contrast agent. An MRI will require an contrast agent or an MRI/MRA.
Do you need an iv for a mri?
No. Some doctors will order MRI with contrast to facilitate better imaging of some body structures. It is not absolutely necessary to have an IV for an MRI but if your doctor believes it is beneficial to have a the MRI with contrast then it best to consent and have the IV.
Why check kidney functions with a blood test before an MRI?
If contrast is going to be usedduring the MRI, kidney function must be adequate to filter the contrast. If they are compromised the contrast can cause a serious disease.
Why would one require an MRI with contrast?
An MRI with contrast is a high-tech medical imaging test that can help your doctor diagnose many different types of diseases. One would require an MRI with contrast if one had a history of tumors, cancers or surgeries.
Does a person need a GFR blood test done before having a MRI?
Not always. Before a routine MRI scan no GFR test is needed. Some MRI scans will require an injection of a drug (contrast) which is used to highlight different aspects of blood supply. There is a small risk of this contrast affecting kidney function so some MRI centres test kidney function before administration. One such test is GFR
